Abstract
The ratios of charged antiparticles to particles have been obtained for pions, kaons, and protons near midrapidity in central Au+Au collisions at roots(NN)=200 GeV. Ratios of <pi(-)>/<pi(+)>=1.025+/-0.006(stat.)+/-0.018(syst.), <K->/<K+>=0.95+/-0.03(stat.)+/-0.03(syst.), and [(p) over bar]/<p>=0.73+/-0.02(stat.)+/-0.03(syst.) have been observed. The <K->/<K+> and <(p) over bar >/<p> ratios are consistent with a baryochemical potential mu(B) of 27 MeV, roughly a factor of 2 smaller than in roots(NN)=130 GeV collisions. The data are compared to results from lower energies and model calculations. Our accurate measurements of the particle ratios impose stringent constraints on current and future models dealing with baryon production and transport.
